Abstract
Test collections are most useful when they are reusable, that is, when they can be reliably used to rank systems that did not contribute to the pools. Pooled relevance judgments for very large collections may not be reusable for two reasons: they will be very sparse and not sufficiently complete, and they may be biased in the sense that they will unfairly rank some class of systems. The TREC 2006 terabyte track judged both a pool and a deep random sample in order to measure the effects of sparseness and bias.Proceedings Title
